When Grace Hournbuckle Walker talked for the last time with her eight-year-old son, Nathan, he shared his joyful hope and anticipation of his future in heaven with Jesus.

Now I Can Think Myself to Mars: A Son?s Final Goodbye, A Mother?s Journal of Renewal collects those writings and bridges the decades between that conversation and the present moment. As you read these words, you will find yourself retracing a mother?s journey of loss and renewal and reliving a boy?s deep and abiding trust in the grace of God. The first set of poems?Book 1: 1992?1997?traverses the thoughts Nathan shared with his mother and her reflections. Book 2: 1998?2008 draws in the writings of Richard T. Walker, Nathan?s father and Grace?s husband, before returning to Grace?s writings. Book 3: 2007?2013 collects inspirational writings, while Conclusion: 2013?2015 ends with letters Grace wrote to Nathan.
